"Ah!"

Su Zimo howled at the skies with widened eyes. His black hair swayed without any wind as his blood qi burst forth.

Bang! Boom! Boom!

Su Zimo's bloodline rumbled, causing thunder to roar and demonic to swirl around him. As his large tendons and bones trembled, his strength had already reached its limit!

Even so, Yu Fei, who was standing opposite Su Zimo, maintained his composure. He gripped Su Zimo's wrists tightly without budging a single inch at all!

This was a complete suppression in terms of strength and cultivation realm!

When the quality of a Golden Core was extremely high with pure spirit energy, it would be able to achieve a harmony with the heavens and earth, forming a phenomenon - that was how Golden Core phenomenons were born.

Because demons did not possess spirit energy, there would naturally be no Golden Core phenomenons as well.
